Q

What are some reasons for fluid loss intraop?

A

Q

What is a situation where excessive amounts of NS may be given because LR is not an option?

What other fluid could you use in this situation?

A

With massive transfusion

You can use plasmalyte with blood to avoid hyperchloremic acidosis

32
Q

Why cant you use LR with blood products?

A

Ca++ binds to citrate and causes emboli

33
Q

Two definitions of massive blood transfusion in children

A
  1. Replacement of one or more blood volumes
  2. Replacement of >30 ml/kg in <4 hours

Or O+ in males???

35
Q

Dilution

Other causes: fibrinolysis, DIC

A

Also not fully researched in children so unsure

38
Q

What occurs to platelets when 2-2.5 blood volumes are lost?

How to prevent?

A

Significant thrombocytopenia and further bleeding

  • Consider platelet transfusion after 1-1.5 blood volumes
39
Q

What is a good determinant of platelet needs?

A

Starting platelet count

40
Q

What occurs when replacing 1-1.5 blood volumes lost with PRBCs and fluids?

Recommendations to prevent?

A

Loss of clotting factors

  • Consider FFP after 1 BV
  • Give FFP after 1 BV loss than 1 FFP: 2 PRBCs
  • Check coags after ever BV loss
41
Q

Recombinant Factor VII (Novo VII) is FDA approved for Hemophilia and congenital factor VII deficiency…

Considerations for off label use in children?

A

Caution in use for children with surgery or trauma induced bleeding

Should only be used for life-threatening bleeding

42
Q

Is TXA an early or late choice for bleeding in children?

A

Early

43
Q

What should you suspect in children with ongoing bleeding with normal pre-op coags and platelet count?

How to treat?

A

DIC

Treat the cause (shock, acidosis, sepsis)

44
Q

What increases risk of hyperkalemia with PRBCs admin?

A
  • Increased PRBC shelf time
  • Irradiation
  • Fast rate of admin
45
Q

T/F hyperkalemia is less likely to occur if blood given at slow rate through peripheral IV

A

True

46
Q

Most common reasons for hyperkalemia during massive blood transfusion

A
  • Tissue injury
  • Rapid transfusion
  • Acidosis (poor perfusion)
  • Hypothermia
  • Hypocalcemia
